IMPROVEMENT IN SLICING-MACHINES.

Specification formiag part of Letters Patent No. l82,el30, datedSeptember 19, 1876 application filed August 2, 1876.

To all whom it may conccm:

Be it known that I, KARL FRANZMANN, of Quincy, in the County of Adamsand State of Illinois, have invented a new and useful Improvement inSlicing-Machines, of which the following is a specification, :referencebeing had to the accom'panying drawings.

The invention relates to an improved mechanism for slicing; and consistsin the devices hereinafter more fully detailed.

The object of 'the'invention is to provide a convenient device forrapidly and smoothly severing slices of material of any desiredthickness.

Figure 1 is a front elevation of a device embodying the elements of theinvention. Fg. 2 is a central section of same through the line 1 2 ofFig. 1.

In the accompanying drawings, A represents the rear support of thetrough, composed of the table B, having the friction-roller a near itsfront edge, to facilitate the movement of the material to be operatedupon, which is confined in place by the sides or guides b, provided uponeach side of the table, and having at their front lower corners the legsD D', which, with the support A, sustain the device. The front of thetable is beveled, and has an upward-projecting edge, secured below whichis a plate, E, having an edge similar to the table, and properlyseparated from the table by an interposed layer of material. These edgesassist in preventing the` retraetion of the material being operatedupon. The front edges of the sides and legs are bound with a strip ofmetal, F, the surfaces of which are in the same plane, and slightly inrear of the plate E. Below the ends of the strips F, at suitable heightsto suit the inclination of the knife, are provided the shoulders H,below which, and opposite the strips, are placed the guides I I',between which and the strips the knife operates, the guide I beingprovided with the loop d, to prevent the escape` of the knife. From theouter side of the leg D, and firmly secured thereto, projects thestandard L, through the outer end of which passes one end of the fixedshaft e, to which one end of the coiled spring M is secured, and. whichpasses between the two pivcoiled, it being confined on the bar betweenthe ends of the pivot-stands.

The bar P may, as in the present instance, be made removable, so thatthe knife may be taken off for grinding.

The center, or that part of the spring about the bar P, is slotted toreceive the end of the knife, having in it the eye f, through which thebar P also passes. Beyond the eye f the knife R has the arch h, beyondwhich is the cutting-blade i, the opposite extremity being provided withthe handle l, which is preferably curved. The knife in its initialposition inclines upward from the bar P at a suitable angle, and restsupon the shoulders B, which are placed and inclined to suit the positionof the blade. To tle inner side of the leg D' is secured one end of theplate V, inside of which, and in the leg D', is cut the recess m, toreceive the sliding bar n, which extends beyond the front of the device,and is provided with the tubular angular guide p, to receive the lowerpart of the gage W, and provided with the set-screw t, to regulate theheight of the gage. A set-screw, u, passing through the leg, serves toregulate the position of the bar n. The gage W extends upward at rightangles to the upper surface of the table, and is flattened and bent to asuitable angle, which comes opposite, above, and in front of the table,and as it can be elevated or lowered, as well as moved forward orbackward, it serves accurately to determine the thickzness of the sliceof material to be severed. V

In operation, the knife is elevated, the material placed upon the tableand pushed forward until it comes in contact with the gage. The knife isnow drawn toward the person, which coils the spring M, and gainstension. The knife is now forced downward through the material, and thepower holding it somewhat reduced. This permits the spring to operate,giving the knife a downward draw movement in the opposite direction, andsevering the slice with a draw-cut.
